We consider the problem of designing a cooperative multiple-input multiple-output (MIMO)
wireless network, where a multi-antenna source-destination communication link is assisted …

This paper investigates a multiuser MIMO relay downlink system with imperfect channel
estimation and limited feedback. We analyze the achievable rate loss due to channel state …

A system with multiple transmitters (ie base stations) and multiple receivers (mobile nodes)
is considered. The transmitter-receiver pairs are assumed to operate using the same …

In this paper, we consider robust joint designs of relay precoder and destination receive
filters in a nonregenerative multiple-input multiple-output (MIMO) relay network. The network …

In this paper, we study the degrees of freedom (DoF) of the MIMO relay networks. We start
with a general Y channel, where each user has M i antennas and aims to exchange …

In this paper, we study a network information flow problem for cellular multiuser two-way
relay networks (MU-TWRNs) where uplink and downlink messages are exchanged through …

This article analyzes the diversity order of several proposed schemes, where the transmit
antenna selection (TAS) strategies are combined with low-complexity decode-and-forward …

In this paper, we propose a closed-form (ie, without the need of any iterative procedure) joint
optimization framework of the source precoder, the amplify-and-forward relaying matrices …

We consider the down-link of multi-pair two-way decode-and-forward (DaF) relay channel
with multiple antennas at all the nodes. We propose schemes composed of relay pre-coder …

Recently, a multiple-input multiple-output (MIMO) two-way X relay channel, where two
groups of source nodes each having 2 nodes exchange independent messages via a …
